I need to apply a css class to invalid controls on a web form. I'd like to make it a resusable class. This is what I have so far:
public class Validation
{
public static void ApplyInvalidClass(Page page, string className[code].....
The problem is what I call this on a .Net user control, I guess because I'm passing in Page, page.FindControl(bv.ControlToValidate) is always null.Is there a better way to do this?
i have created loing form and create user form. then how to apply login rights..? i have 2 types of user. admin and normal user admin can move and use all pages while normal user can acces limited pages.
View 4 RepliesI've got a Login control on a page, I'm trying to style the hyperlinks used in the control (e.g. forgotten password link). I've got a theme containing a stylesheet where I've defined link classes. I set the CssClass property of the HyperLinkStyle property of the control, but it has no effect. All other areas in my page where I use stylesheet classes it works, except for this login control.

I am relatively new to asp.net environment.Recently working on a project, i discovered a problemi.e. I had to add using system.io to all file functions in any page. same for using sql functionsi.e. any method for that namespace had to be used in full like By adding the following section in web.config , ALL my pages automatically have access to that namespace
<namespaces>
<add namespace="System.Data"/>
<add namespace="System.Data.SqlClient"/>
<add namespace= "MySql.Data.MySqlClient"/>
<add namespace="System.IO"/>
</namespaces>

I'm working on a multipage form in .Net using AJAX (UpdatePanels). I am stuck right now trying to get a class added to the textbox that is invalid to basically highlight it red.
I found a sample online using this code:
$("span.invalid").bind("DOMAttrModified propertychange", function (e) {
// Exit early if IE because it throws this event lots more
if (e.originalEvent.propertyName && e.originalEvent.propertyName != "isvalid") return;
var controlToValidate = $("#" + this.controltovalidate);
var validators = controlToValidate.attr("Validators");
if (validators == null) return;
var isValid = true;
$(validators).each(function () {
if (this.isvalid !== true) {
isValid = false;
}
});
if (isValid) {
controlToValidate.removeClass("invalid");
} else {
controlToValidate.addClass("invalid");
}
});
That works perfectly, in IE only. For some reason this code does not ever fire in Firefox. I've looked up the DOMAttrModified event and it sounds like this should work in Firefox, hence it being in the code. I must be missing something though because it does not work.
I'm open to other solutions for what I am trying to accomplish here if anyone has something good. Basically the form is 3 pages right now. Page 1 has a variable number of fields that require validation. It could be 5, or 13 fields, based on a checkbox. Page 2 has another set of fields that need to be validated separately. Obviously when I am on page 1 it should not try to validate page 2, and vice versa.
I've got the following View
[Code]....
The problem is that when I submit a blank form back to the controller, I get redirected to the "its valid" page, meaning that the form passed validation.
What might I be doing wrong?
(Using ASP.Net 2.0 on Visual Studio 2005, coding in C#)I write in the hope that someone will be able to provide a clue as to how I might best overcome this issue:I've got a form with 2 RequiredFieldValidators, and 2 buttons. Button 1 has 'CausesValidation' set to 'False', and populates some of the other fields on the form from the database (via a postback).Button 2 fires the validation, then if the form is valid brings a javascript popup confirmation box and then, if true, it puts the data in the form into an email.All this is working fine. However......My problem is this: If I press button 2 with my required field(s) empty, the form quite correctly refuses to submit, and highlights the appropriate field(s) with a red *.But: if I then press button 1 (my populating button) it DOES NOT FIRE until I press it a second time!Code snippet follows (markup only - I will of course post code-behind if nec. but I don't think it is)
<script type="text/javascript">
function ConfirmSubmit()
{

I've got my validation wired up through my Service layer, and my Birthdate property looks like this.
[Code]....
The client side validation works properly if I input something like `12/12/1990` but when the form is submitted, the server side validation trips and I'm told the entry is invalid. I'm using the jQuery-UI Datepicker to input the date, however when I disable the datepicker, the problem persists.Am I missing something here? I thought the client side and server side would be the same thing.If I remove

Then the form submits. It's obviously something to do with the Regex.
Using ASP.NET VB, I have a form with some text boxes and a Gridview. If a user clicks the Edit button on a row in the gridview, and then tries to submit the form with a row still in edit mode on the Gridview, this error is generated -
"Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. "
I created a method in my class which will determine if an input is a numeric value or not.
Code:
[URL]
And even I input a numeric value in my entry, still I get the error message "Invalid entry". Can anyone from this community have an idea on how am I going to solve this issue.
I am using <%# MyFormatClass(Eval("fieldname")) %> to display data in a grid view on my page. MyFormatClass works fine, but now I want to move it to a central location that can be used by many pages. When I try to access the class <%# Utils.MyFormatClass(Eval("fieldname")) %> it no longer works. Is this something we are allowed to do?

View 4 Repliesgot a question regarding form validation via entity partial class. I created my edmx-file with the Entity Data Model. Now I am trying to validate my form inputs via this partial class:
[Code]....
Edmx file and partial class are in the same namespace. But the partial class does not get fired. My controller file looks like that:
[Code]....
This is an ASP.NET 2010 web app written in vb. I use several Session variables. I want to pass them all to a central class and let the class manage them. However, I am having some trouble.
Here is the code on the calling page:
Dim arrGoodSessions() As String ={"nameofsession1", "nameofsession2", "nameofsession3"}
Utilities.ManageSessionVariables(arrGoodSessions)
It calls that static Utilties class. I have set a reference to System.Web. Here is the code in the class:
Imports System.Web
Imports System.Web.SessionState
Imports System.Web.SessionState.HttpSessionState
Imports System.Web.HttpContext
[Code]....
This attempts to simply read in some names of session variables and then cycle through all session variables and remove any I didn't list. This works when all of the cod eis on the page. But when I move this to the class, it doesn't recgonize Session.Contents.
I am beginner to MVC. I have created a View with dropdownlist, text box and text area. I didn't create a strongly typed view because these fields are not generating from the database. Is this right way of doing it? Do I have to create a 'Model' class and generate a strongly typed view? I am trying to validate(client and server side) these fieds before saving into the database. How to create a Model class for these fields?
Here is my view looks like.

This not an 'MVC' question per se, but this is the closest forum I could find. I am building web/wpf/silverlight front end on the MVP pattern. I am using EDMX and a 'business logic' class to form the model, a presenter project, and a view project.The IViews contain the basic structure of each entity, the presenter contains actions, etc.Sample view:
[Code]....
Sample presenter:
[Code]....
QUESTIONS:I seem to end up with a 1-1 mapping of views and presenters. SHould there be more than one view per presenter, or more than one presenter per view? Should the presenter for an entity (in this case a User) also contain methods for functional items such as searching for a filtered list of Users using overloaded methods, etc.?Should the IViewXYZ interface contain any events or actions (methods)?
I have a Custom WebControl. Inside this control I add a button and I want it to access an EventHandler that is on the WebForm where the control is included. The handler handles with controls from the WebForm, so it has to be there. I could probably manage to take the button out of the control, but it would be better to keep it on the control, for organization sake.

I created a Class library for WCS service (MyWCFServiceLibrary) to access data form my database. The database connection strings have been defined in Properties->Settings.settings. The endpoints are defined in the app.config. Tracing and logging is set to write to files on local server. This service is hosted by a .net web service. This webservice refrences the WCF service using MyWCFServiceLibrary.dll and MyWCFServiceLibrary.pdb. The web service is hosted in IIS. All this setup is working fine on the development environment.Now I want to deploy this in the QA environment. Since I am a newbie with WCF, I would appreciate some help on what needs to be done for deploying this on the QA server.1. Do I need to recompile the MyWCFServiceLibrary.dll after changing the connectionstring to point to QA database and tracing and loggint paths to the new server?2. Is there anything that needs to be done with end points or anything else?
